Monkey D. Luffy finally achieved his dream of becoming the King of the Pirates. After the adventures on the Grand Line in the world with pirates and heroes, he managed to gain the legendary treasure that made him the King of the Pirates--the One Piece. However, that minute of joy didn't last as the evil pirate Blackbeard took the treasure for himself and killed the young pirate in front of his entire crew. Three years passed prior to his death, and Luffy finds himself to be reincarnated to a boy named Izuku Midoriya, who was sadly born Quirkless into this world. Seeing how his world has changed and Izuku needed encouragement, Luffy helped Izuku train with his new power of rubber. With this, and some help from his other mentor, All Might, Izuku heads down his path to becoming the greatest Hero of them all. ...and may be get revenge against Blackbeard.

Barbarossa Kaishu transmigrates to one piece and becomes the older brother of Kaidou of the Beasts while possessing a stronger physique talent! After the Battle of the Gods Valley, the Strongest Assistant system was activated. It can continuously improve the loyalty of the crew members while letting their Zoan-type devil fruit evolve. Sengoku: Why all of the Beasts Pirates are Mythical Zoan Devil Fruit Users?! Five Elders: Damn it! How can the Beasts Pirates be scarier than Rocks Pirates? Garp: My iron fist can't break even Kaishu's defense at all! Imu: How can there be such a terrible monster? Why even Uranus can't kill Kaishu!!

(Y/N) (L/N) has always been treated like a monster. It could be because he ate something called a Devil Fruit, or because there's something weird that's inside of him. Something evil. However, that all changes when he meets a pirate crew that's far from ordinary. He's about to embark on the greatest adventure of his life and maybe find the love of his life. Note: I do not own One Piece. All rights belong to their proper owners.

Meet Jason, soon to be a widely known infamous pirate called Diddy D. Kong, but before we get that far, let's rewind time a few hours. Jason was just your everyday man, maybe not every day, as he was a large man covered in muscles, infatuated with the concept of strength; however, before he could achieve his dream of becoming the strongest, he died of a heart attack in his sleep, though, luckily for him, that wasn't the end as he was reborn in a world where chaos runs rampant in the form of pirates. Now born in a world where his dream of becoming the strongest is achievable, watch as he slowly carves his way to the top in the body of a powerful race, along with help from some friends that'll accompany him on his journey.

After Gol D. Roger's dying words drove all kinds of people to the sea to chase after dreams that only the Grand Line could satisfy, two young kid's worlds would be changed forever. Monkey D. Luffy and Portgas Akari (who took Ace's surname because she saw him as close to an older brother as anyone, and he insisted she take it) have the pleasure of meeting 'Red Haired' Shanks, and thus paving the way towards them wanting to become pirates. Now at the age where they can set out on their own, Luffy and Akari have begun their pirate journey, and it is all uphill from there. [Thank you for the amazing cover by @ktjhs_kay. It is so pretty and I love it!] (The only thing that is mine is Akari, everything else is thanks to the brilliant mind of Echiro Oda. Without him, Akari would have found no home.) (#1 in LuffyxOC tag, so that's pretty cool!) (#1 in MyOC tag, so that is cool!)
